What is this case mainly designed for?

The A17 Slim Shockproof Case is designed around two core functions: shock protection and cooling support. It combines raised Avient corner protection, a slim shockproof structure, CoolHyper cooling with a silicone pad and aluminum plate, and a technical design built for everyday wear resistance, grip, and full-device protection.

Will using a phone case make the phone hotter?

Some standard phone cases can make heat harder to dissipate. The A17 uses a superconductive silicone cooling pad, an integrated aluminum plate, and a heat-management structure to help guide heat away more efficiently and reduce trapped heat buildup. Actual cooling performance may vary depending on your device, environment, and usage load.

Does this case support MagSafe and magnetic accessories?

Yes. The A17 Slim Shockproof Case is designed for use with magnetic accessories such as magnetic stands, car mounts, wallets, and magnetic power banks. Magnetic strength may vary depending on the phone model and accessory used, so we recommend using MagSafe-compatible accessories and keeping the phone properly aligned for a more stable experience.

Does the case protect the camera lens when placed on a table?

Yes. The case features an elevated lens design and a protective camera area to help reduce direct contact between the camera module and flat surfaces. This helps lower the risk of everyday scratches and set-down wear when placing your phone on a desk or table.

How should I clean the case?

Wipe the case gently with a slightly damp soft cloth. For tougher stains, use a small amount of mild neutral cleaner and wipe carefully. Avoid strong corrosive cleaners, abrasive tools, or soaking the case in alcohol for a long time, as this may affect the surface finish or hand feel.

Will the color-changing temperature indicator always react the same way?

The color-changing temperature indicator responds to temperature changes and may show different color levels as heat rises. Its reaction speed and visible color range can vary depending on ambient temperature, heat source location, phone workload, and how long the device has been under load.

Will the case turn yellow over time?

The case includes light-colored TPU/TPE components, and long-term exposure to UV light, heat, sweat, or daily residue may cause slight color changes over time. To help keep it looking better, avoid extended direct sunlight and clean the case regularly.

Will installing or removing the case scratch my phone?

When installed correctly, the case should not scratch your phone. Insert one side of the phone first, then gently press the remaining edges into place. Avoid trapping dust, sand, or hard particles inside the case. If the case is used in sandy or dusty environments, remove and clean it before reinstalling.
